Secret Tunnel
Level 2: Drive through the course as usual until you come to the
free-way overpass that can be jumped. Now, instead of jumping down to
the road beneath angle the car so that it is going from right to left.
If you go off the free-way just right you'll fly across the gap to the
other side of the freeway where a secret loop and two keys await.
Once you've made it you'll be treated to a red loop of endless
possibilities
Pappy Land
Pappy Land, a secret stunt course hidden in track 6, is located at the
bottom of one of the many mountains in the level. To find it, follow the
pathway which passes a white citadel (at top of mountain) and then leads
into the dirt path which, if taken wrong, can send cars barreling over
the edge of the cliff. Pappy Land is located directly over the
mountain's cliff facing away from the citadel. It's at the bottom of the
mountain right next to the ocean, so be careful making the trip down.
Inside the secret cave is Pappy Land, an immense setup of jumps, loops
and walls
